all that with only 30# injectors? is the nitrous system a wet or dry kit? if its dry, i think you'll be running into some serious fuel issues.

If you got an aftermarket block and custom cam, I like the 205 idea.

Upgrade those injectors with the nitrous shot.

It really depends on a lot of factors, like what accessories you have, cam grind, etc.

You could pop 400rwhp, rougly speaking.

It will probably be close to 400rwhp on motor.

Click to expand...

It doesn't have stock internals since it's a 347. But, if you're running a stock block and spray it, it will probably end up as two inline 4 cylinders and toss you're new stroker kit through the heads. Good luck.
